Our GLL Car Pitman Arm uses high-strength alloy steel (such as 40Cr or 4140 alloy steel) as the main material. GLL materials have excellent mechanical properties and corrosion resistance. Through precision heat treatment technology, the surface hardness and internal toughness of the material are perfectly balanced, which can not only withstand the high-frequency impact of the steering system, but also resist wear under complex road conditions. Compared with traditional cast iron or ordinary steel, the fatigue life of our GLL products is increased by more than 30%, ensuring long-term use without deformation or loosening.
Our GLL car pitman arm has many innovative advantages.
Structural optimization: GLL car pitman arm adopts topological optimization technology to reduce weight by 18% while maintaining strength. The unique "double arc" transition design effectively disperses stress concentration and avoids metal fatigue caused by long-term vibration.
Surface treatment: GLL car pitman arm adopts military-grade electrophoretic coating + anodizing dual anti-rust process, and the salt spray test is more than 720 hours without rust, which can adapt to harsh environments such as coastal high humidity and northern snow melting agents.
Modular design: GLL car pitman arm provides a variety of specifications to adapt to 95% of global models, especially for SUV, pickup and other heavy-duty models to develop enhanced versions, with a load-bearing torque range covering 2000-6000N·m.
Our GLL car pitman arm adopts advanced precision forging technology and is formed in one go using a 10,000-ton forging press, making the metal fibers denser and reducing the internal defect rate to below 0.02%. Compared with the casting process, the forged pitman arm has a 45% increase in strength and a torque bearing capacity that exceeds the conventional industry standards. Fine grinding is performed with a CNC machining center to ensure that the tolerance of each mounting hole is controlled within ±0.02mm, achieving seamless matching with the steering system.
Our GLL pitman arms widely used in the steering systems of various types of vehicles, including sedans, SUVs, trucks and off-road vehicles. In addition, GLL pitman arm is also widely used by many auto repair and modification companies. Whether it is new car manufacturing or old car repair, GLL products can provide excellent performance and reliability.
